I used to do it without looking at my phone, now with touchscreen I lost that ability, I have to check every word, some keyboards help with that correcting my words if I moved my fingers a little to the side, but it's not the same, with physical buttons I was sure I pressed the correct buttons. Physical buttons give touch feedback and that's important when you're focused on something important in your screen. I don't want to switch my focus from my screen to my keyboard every time I need to use a function key.
I almost always text on my phone without looking because the visual effect where the selected letter appears above your finger actually makes me slow down. I was never able to use physical phone keyboards as easily as the adaptive software ones on modern phones.
Also I use vi mostly so I only use function keys rarely, in which case I look up.
edit: wrong year
Because programmers are at least as fond of hyperbole as the reality television programming they all claim to hate.
I haven't used it yet, so I can't judge it too much, but I imagine Escape actually works well since it's the top corner of the keyboard and easy to feel, if escape were anywhere else it would really suck.
I've got a keyboard with clicky button-type Esc and F keys, which might be a fair approximation to the new F key strip. (Pressing them isn't a million miles away from clicking on the Force Touch trackpad.)
It's bearable, but not really very nice.
Confirmed correct:

And you can use ctrl [ instead which is closer to the home row anyway.
The nice thing is with this touch bar thingy that's possible.
As long as it's supported by the program, of course.
What if you wanted to use mc (The Midnight Commander), which relies heavily on F keys? wait for the update?
And no, I don't think remapping it is a great idea.
If I had to use this for work I would protest.
